MACHINE FOR PEGGING BOOTS AND SHOES.

Specicaton of Letters Patent No. 17,544, dated June 9, 1857'.

T o all whom it may concern:

Be it known that I, BnNJAMiN F. Srinifrnvnix'r, ot' Boston, in thecounty of Sutiolk and State ot' h/Iassachusetts, have invented anImproved Machine for Pegging Either Boots or Slices; and I do herebydeclare that the saine is fully described and represented in thefollowing specification and the accompanying drawings, of which- Figurel, exhibits a top view of said niachine; Fig. 2, a vfront elevation ofit; Fig. 3, a rear elevation of it; Fig. 4, a central vertical andlongitudinal section of it; Fig. 5, a front end view of it.

Such other figures as may he necessary to a complete description anddelineation of said machine will be hereinafter referred to andexplained.

In these drawings, A, denotes the frame of the machine, the samecarryinga driving shaft, B, arranged therein as shown particularly inFig. -which is a vertical and transverse section taken through the axisof Y the driving shaft. On the said driving shaft are fixed two groovedcams, C, D, side views of which are given in Figs. 7 and S. These camsrespectively operate two bent levers, E, F, a projection from each ot'the levers extending into the groove of its working cani. In Figs. 7 andS the dotted lines Gr, drawn across the face ot each cam serve ltoillustrate the relative positions of the two earns on their shaft, thesetwo lines being brought into one plane with one another at the time offixing the cams on the shaft. The lever, E, at its front end is jointedto a carriage or slide, H, of the awl carrier, I, and serves to impartto such carriage, H, its longitudinal and vertical movements. The awlcarrier is a cylindrical rod or slider constructed with an arm, a,extend ing from it at right angles as shown particularly in Fig. 9.which is a slide view of the carriage or slide, H, the awl carrier, I,and the slotted cylinder Y) applied to the awl carrier and operating inconnection with a stud or roller, c, to impart to said awl carrier areciprocating lateral motion such as may be necessarj7 to carry the awlnot only1 directly over the peg hole or passage, (Z, through the rest,K, but also to move the awl out of the way of the same as circu1nstancesmay require. In Figs. 3 and 4L, the

small stud or roller, c, is represented as pro jecting inward from theinner side of a rec tangular opening made in the frame, A, and asentering the slot, 0, of the slotted cylinder, Extending` from the awlcarrier downward is the awl, Behind the inner side of the upper arm ofthe lever E, there is arranged as shown in Fig. 2 another bent lever, L,which turns ona stationary fulcruni, g,` and has a curved slot, z, madethrough its upper arm Into this curved slot a stud, z', projecting fromthe lever, E, enters the, slot in the arm serving to produce a verticalmovement of the lever, L. while the lever. E, is being put in motion. Atits 'front end the lever, L, is jointed to a vertical slide or carriage,M` of the peg carrier, N.

In Figs. 10 and l1 are represented side views of the peg carrier N, andits carriage. M, the same answering also to illustrate the slottedcylinder, la, that is fixed on the peg carrier and serves to rotate ittransversely as may be required. A stationary stud, Z. projecting fromthe frame A, (see Fig. 3) enters the groove, m, of the slotted cylinder,7c. The lower part of the peg carrier N, consists of an arm, n,extending horizontally from the rotary and sliding rod or part, o, otthe carrier, the said arm being made to support a vert-ical tube, y),whose oiiice is to separate a peg from a strip of peg wood and transfersaid peg directly over the peg passage, (l. ot the reist K, in orderthat the peg driven may be forced downward through the tube 79, and soas to torce the peg down out of the same and `into and through the pegpassage, and from thence through the rotary feeder wheel to behereinafter described.

Fig. l2 exhibits a top view of the peg tube y), and represents it asformed with a cutting edge (j. Fig. 13 a vertical sec tion of said pegtube.

The heut lever, F. serves to operate the bentl lever, O, formed andarranged as shown in Figs. i and 2, and made to turn on a tulcrum pin.An angular slot, S, is formed in the upper arm of the lever, O, andreceives a stud or projection, t, extended from the -lever F. The lowerarm of the bent lever, O, is provided with a slide 1", a, that slideslongitudinally in it, see Fig. 14:, which is a. horizontal section ofthe slider and arm. From the inner side of the said slider vstood fromwhat follows.

a stud, e, projects and enters a groove, t0, made in a slider, P, whichis arranged 1n rear of the lever, O, and plays vertically between guidesThe said slider, P, at its lower end has a springpawl, y, hinged to itand made to extend downward and work in the teeth of a ratchet, e, fixedon the rear end of the shaft, a, of the feed wheel R, the said ratchetshaft and .feed wheel being particularly shown in Fig. 4 and also inFig. 15, the latter figure being a top view of them as detached from theframe.

Fig. 16 exhibits a front view of the slider, P, while Fig. 17 is atransverse section ot the same, the spring pawl y, the ratchet e, andthe spring retaining pawl of the s aid ratchet, such spring retainingpawl being exhibited at b, in the said figure and also in Fig. 3.

From the above it will be seen that when the bent lever, O, is moved onits fulcrum it will produce vertical motions of the slider P, and itspawl y, whereby an intermittent rotary motion will be imparted to theratchet a and as a matter of course to the feed wheel R.

Before proceeding farther it may be remarked that the object of the feedwheels, R, is to move the shoe and last along with an intermittentmotion such as may be necessary to enable the pegs to be driven into thesole of the shoe. For this purpose the feed wheel has the shoe borne upagainst it by mechanism which will be hereinafter described.

The object of t-he slider, u, is to enable the bent lever, O, to impartto the pawl g/,/vari able vertical movements. when the slide is drawnout to its greatest extent it carries its stud o, twice the distancefrom the axis of thefulcrum r that it is when the slider is pushedentirely back.

ward. Consequently during the reciprocating movements of the lever, O,the ratchet will be vmoved twice as far when the slider, u, is drawn outas it will when the said slider is forced entirely backward wit-hrespect to the lower arm of the lever, O. The faster rotary movementthus imparted to the feed wheel, R, is for the purpose of enabling themachine to perform the pegging of but i a single row of pegs at oneoperation. Two rows of pegs are introduced into the sole when the slowermovement is given to the ratchet as will be more particularly under-Attached to the lower arm of lever, O, (as shown) and so as to projecttherefrom as shown in the drawings is a spring, S, carrying a pin orstud, c', that extends through the lever and slides therein. This springis provided with an inclinedv cam, CZ, which rests against the side of apin or stud, e, which extends upward from the slider, u, the whole beingarshaft to move endwise with the slider.

For instance,

ranged so that when the slider is drawn forward it shall cause thespring, S, to'move laterally away from the lever to the extent sufcientto draw the pin, c, out of engagement with the tripping click, f, of alever, g, arranged on the frame and on a fulcrum z, as shown in thedrawings.

Fig. 18 exhibits a view of the lever, the tripping click and the springfor operating the same t-he whole being exhibited in rear elevation. Thetripping click made tapering at its upper end turns on a fulcrum z" andhas a stud lextended from its lower arm into a short slot Z formed inthe lever g. The slot determines the extent of the vibration of thetripping click relatively to the lever g. A spring, m, fastened to theframe, A, and shaped as shown in the ligure last mentioned extendsbetween two pins, n, n', projecting from the. rear side ofthe tripping,click.. The foot of thelever-g, is jointed to a slide rest, 0', seeFigs. 4 and 5, such slide rest being also shown in underside view inFig. 19. A. projection p from the rear end of said slide rest enters agroove o made in a shaft a, the same causing said During thereciprocating movements of the bent lever, O, the pin c will be carriedfirst against one side and next against the other side of the trippingclick f, so as to produce intermittent vibratory movements of the lever,g, on its fulcrum, 71,, whereby an intermittent forward and back orlongitudinalmovement of the slide rest 0 and the feed wheel, R, will beproduced and so as to so move the shoe that pegs may be insertedin tworows into its sole, the pegs being driven alternately in said rows. y

The feed wheel, R, is formed with tw ranges or series of holes extendingradially through it as shown at, s, and t', those of one range beingdisposed so that each one o-f them shall not be exactly opposite one ofthe other ranges, but be between two of them as shown in the drawings.Besides this the external surface of the feed wheel is fluted so as toenable it to move the shoe when pressed against the same and the feedwheel isin rotation. VDuring the operation of pegging a shoe, this feedwheel has imparted to it an intermittent rotary motion and every timeits .movement is arrested one of its holes will be brought directlyunder and in a straight line with the passage cl, so

as to enable either the awl or a peg to be driven down through it andinto the shoe.

A peg driver carrier or slider, T is arranged so as to stand verticallyand to play up and down directly over the peg passage, d, and it ismoved by the lever, F, with which it is jointed. This slide T, carries apeg driver u, which consists of a steel wire or rod of a length.sufficient when driven downward to force the peg through the peg carrierN, and into the sole as far as may be necessary. On the rear side 'ofthe gooseneck a or projecting arm of the frame A, is a shelf QU which isprovided with a projecting guide and a broad spring y, arranged on it asshown in the drawings. The said spring serving to press one or morestrips a?" of peg wood up against a feeder z, see Fig. 20 which is ahorizontal section of said feeder and spring and made to represent theshelf fm and a pack of peg wood arranged thereon, the latter being shownin dotted lines.

Fig. 9.1 is a side view of one of the strips of peg wood as prepared forthe machine, Fig. 22 being an end view of the same.

Vhen each strip is being applied to the machine it is placed on a shelf`w and so that the guide m shall pass into the space between the firsttwo teeth or angular points of the. said strip. The guide ai serves notonly to properly adjust the peg wood strips but it prevents all but theone which is directly against the feeder .2" from being moved forward orbackward by the action of the feeder. This feeder is serrated orprovided with spring teeth as shown in Fig. 23. which is a side view ofit, and besides this there is a retaining serrated spring c"extending'through the feeder and fastened to the goose-neck o and madeto rest against the inner strip of peg wood so as to prevent it frombeing drawn backward during a retraction of the feeder. The feederslides horizontally and is moved by the action of a bent lever, 1),which turns on a fulcrum c, is jointed to the feeder and rests at itsfront end on a bracket, or stop, c, arranged as shown in Figs. 3 and 5.A spring, (Z2, is applied to the shelf in and so as to press downwardthe lower arm of the levert. From this arm there is an extension shapedas shown at` 0. Vhile the slide, M, of

the peg carrier, N, moves laterally toward the peg wood its arm on whichthe peg carrier is situated passes directly underneath the extension 0and so that when the peg carrier is lifted upward it shall so move thelever 7) as to cause the feeder e to be retracted. On the descent of thepeg carrier, N, the lever 7) will be moved in the opposite direction bythe spring d, and consequently will force the feeder forward so as toadvance a strip of peg wood against the end of a stop lever f arrangedas shown in thel drawings. This stop lever is forced downward b v aspring g, acting against a projection from its upper arm. The tail ofthe lever extends through a locking slide 71.." which is placed againstthe under side of the shelf, and slides endwise. An underside view ofthis locking slide is given in Fig. 24. The position of the tail of thestop lever and the recess of the slide in which said tail acts beingtherein shown. When the peg carrier rises upward to separa-te a peg fromthe strip of peg 'wood it elevates the stop lever f and this latterforces the locking sli-de 71. underneath the end of the lever Z1", whichat the same time is raised upward, and this lever will be so held upwardor prevented from moving the feeder forward until the peg carriers haspassed downward beyond the strip of 'peg wood. As soon as this takesplace the tail of 'the stop lever f, acting against the locking boltretracts it so as to allow the lever b to descend; the peg wood beingdriven forward at the same time. The stop lever and its bolt or slidethus prevent the feeder from being driven forward while the peg carrieris directly in front of the strip of peg wood, as under suchcircumstances, should the feeder be advanced it could not carry the pegwood with it, but would be likely to cut into and injure it.

The next portion of the machine to be described is that for holding theshoe in a proper position to receive the pegs during the entire`operation of pegging its sole. For this purpose there is employed ajack of peculiar construction. It consists first of a lever, U, whichturns vertically on a fulcrum as shown at, 27, and has a weight la soapplied to its rear arm as to be capable of being adjusted in positionnearer to or farther from the fulcrum as occasion may require. The frontarm of this lever is connected by a universal joint, m, with a standardZ. The standard being shaped as shown in the drawings. On an arln orprojection n from the standard the last, V, is supported as shown in thedrawings. This last has a rod 0 projecting down from it and through thearm a and a lever 7) extending from the standard and turning on a rod,r. as a fulcrum. This lever rests on a shelf s, projecting from thestandard and carrying a rack t arranged on it as shown in Figs. 2 `andThe hole made through the arm n for the reception of the rod o should beconstructed somewhat larger than the said rod in order to enable thelast to turn or move on the arm a as occasion may require. The rod oinclines backward a little from the vert-ical line so as to tip the soleof the last in such manner as to bring properly against the feed wheel,R, during` the rotation of the shoe, that port-ion of the sole of theshoe into which the pegs are to be driven. The objectof the lever pconnected with said rod 0 is to enable the workman or attendant to tipthe last, V, longitudinally more or less during its rotations in orderthatthe pegs may be driven as near as possible at right angles to theouter surface of the sole. The weighted lever u maintains the shoe inclose contact with the feed wheel, R, and enables it to move upward ordownward as occasion may require while it is being turned around underthe operation of the feed wheel. It also serves to press the solesfirmly together, and to the last, while the pegs are being driven.

Having thus described the construct-ion of said machine, I would remarkthat while its driving shaft is in rotation the awl will be turnedaround laterally and driven downward through the peg passage and intothe sole. Immediately afterward the awl will be drawn from the sole andpeg passage, andthe peg carrier will be turned around so as to comedirectly over the peg passage. NeXt the peg driver will be forceddownward through the peg carrier and peg passage and so as to drive intothe sole the peg which may be in the peg carrier. diately afterward thepeg driver will 'be raised upward out of the peg carrier. Next both pegcarrier and awl will be moved laterally, the former being carrieddirectly under the strip of peg wood while the other will be movedimmediately over the peg passage. Next the peg carrier will be raised upand the awl forced downward, the former during its upward movementseparatving a peg from the strip of peg wood. In' order 'to insert butone row of pegs into the sole the slider, u, is to be drawn forward butwhen two rows are to be inserted it is to be pushed backward.

Having thus described my improved machine what I claim therein as of myinvention is las follows,

l. I claim in combination with the feeder wheel, R, and its rotarymechanism a mechanism for imparting to said feeder wheel and the lastreciprocating, intermittent end-j wise movements whereby the pegging oftwo ranges of pegs may be effected as described.

2. I do not claim a toothed or corrugated feeding wheel, nor one madewith a seriesA of holes for the pegs to pass through or into, but what Ido claim is constructing theA feed wheel, R, with two series of radialholes arranged in it as speciiied.

3. I also claim the stop lever f and its locking slide L in combinationwith the peg wood feeding mechanism and made to,

therewith substantially as eX- .wood feeder and .the feeder, R,subst-antiall y as specified.

o. I also claim the combination of mechanism for producing areciprocating intermittent endwise movement of the feeder wheel, R, thesame consisting of the slider u the stud, o, the groove w the spring Sthe pin c t-he inclined cam cl thepin c the tripping click f the lever gand the slide rest 0 the' whole being applied together substantially asspecified.

6. I also claim combining with the mechanisin for producing thereciprocating endwise movement of the feeder, R, a weight ed arm or itsequivalent applied to the pegging jacl substantially as above specifiedwhereby the shoe and lastare maintained in close contact with the feederand permitted to :move in correspondence therewith substantially as setforth.

7. I also claim the method of effecting the Vfeeding of the peg wood,that is by the slider, M, of the peg carrier the lever b2 the serratedfeeder e and the spring d2 operating together as specified.

In testimony whereof I have hereunto set' my signature.
